( Bermuda, although physiographically not a part of the West Indies, has common historical and cultural ties with the other islands and is often included in definitions of the region.) Three major physiographic divisions constitute the West Indies: the Greater Antilles, comprising the islands of Cuba, Jamaica, Hispaniola ( Haiti and the Dominican Republic), and Puerto Rico the Lesser Antilles, including the Virgin Islands, Anguilla, Saint Kitts and Nevis, Antigua and Barbuda, Montserrat, Guadeloupe, Dominica, Martinique, Saint Lucia, Saint Vincent and the Grenadines, Barbados, and Grenada and the isolated island groups of the North American continental shelf- The Bahamas and the Turks and Caicos Islands-and those of the South American shelf, including Trinidad and Tobago, Aruba, Curaçao, and Bonaire.
